WHAT IT DOES

What visual_baseline_save does on Claude Mobile

AI agents use visual_baseline_save to create or update resources in Claude Mobile, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Mobile environment.

RISK

Why visual_baseline_save is rated Medium

This tool creates and persists data (a visual baseline reference file) in a reversible manner. While it modifies state by writing baseline files, it does not irreversibly delete data, move money, or execute arbitrary code—the operation is reversible (baselines can be updated or deleted).

From the tool's definition The tool 'visual_baseline_save' explicitly performs a 'Save current screenshot as visual baseline' action, which creates and stores data (a baseline image file) for regression testing purposes.

RECOMMENDED RULE

The rule that runs visual_baseline_save safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Mobile, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For visual_baseline_save, this is the rule to start with:

visual_baseline_save Rate-limited

visual_baseline_save stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
